Bleeding after abortion is mainly due to the shedding of the uterine lining, which leads to bleeding, and vaginal bleeding due to uterine contractions, which accelerate the expulsion of pregnancy material. There is also abnormal vaginal bleeding due to incomplete abortion after abortion. Irregular vaginal bleeding due to infection of the reproductive system after abortion, which affects the recovery of the uterus. Vaginal bleeding due to damage to the endometrium and the muscular layer of the uterus during abortion. At present, you need to pay attention to observe whether there is abdominal pain, the amount of vaginal bleeding and the duration of bleeding, and whether there is vaginal discharge, odor and other discomforts. Ultrasound examination should be carried out 1 month after the abortion to find out how the uterus recovers and to avoid complications or even hemorrhage.
